Configuration procedure

1) Configuration on Device A

# Configure an uplink policy nest to add outer VLAN tag 100 to the traffic tagged with VLAN 10.

<DeviceA> system-view

[DeviceA] traffic classifier nest

[DeviceA-classifier-nest] if-match customer-vlan-id 10

[DeviceA-classifier-nest] quit

[DeviceA] traffic behavior nest

[DeviceA-behavior-nest] nest top-most vlan-id 100

[DeviceA-behavior-nest] quit

[DeviceA] qos policy nest

[DeviceA-qospolicy-nest] classifier nest behavior nest

[DeviceA-qospolicy-nest] quit

# Configure GigabitEthernet 2/0/1 to forward the traffic of VLAN 100 with the outer VLAN tag removed.

[DeviceA] interface gigabitethernet 2/0/1

[DeviceA-GigabitEthernet2/0/1] port link-type hybrid

[DeviceA-GigabitEthernet2/0/1] port hybrid vlan 100 untagged

# Enable basic QinQ on GigabitEthernet 2/0/1.

[DeviceA-GigabitEthernet2/0/1] qinq enable

# Apply the uplink policy nest to the inbound direction of GigabitEthernet 2/0/1.

[DeviceA-GigabitEthernet2/0/1] qos apply policy nest inbound

[DeviceA-GigabitEthernet2/0/1] quit

# Configure the uplink port GigabitEthernet 2/0/2 to permit frames of VLAN 100 to pass through.
